The incorporation of nanotubes into thermotropic liquid crystalline polymer (TLCP) was reported to enhance the thermal decomposition temperatures and the residual yields of the nanocomposites (35). It was reported that the nanotubes act as protective barriers in the nanocomposites against thermal decomposition and are likely to retard the thermal decomposition of the TLCP nanocomposites owing to building of barrier to hinder the transport of volatile decomposed products out of the nanocomposites.

Recent works in liquid crystalline polymer science, also emphasises more on the use of Thermotropic Liquid Crystalline Polymers (TLCPs) for development of nanocomposites using different nanofillers (Cheng et al. 2012). A discussion has already been made on this in the foregoing discussions. Carbon based nanofillers are more promising in this regards. [Pg.331]

Multiwall carbon nanotube (MWCNT) reinforced thermotropic liquid crystalline polymer (TLCP) nanocomposites were prepared by a melt compounding process. Incorporation of small quantity of the MWCNT improved the thermal stability of MWCNT reinforced TLCP nanocomposites. The rheological behavior of TLCP/MWCNT nanocon sites was dq)endent on the MWCNT content. The complex viscosity and storage modulus of TLCP/MWCNT nanocomposites increased with increasing MWCNT, resulting fiom physical interactions such as the nanotube-polymer noatrix interactions and the nanotube-nanotube interactions. This increment effect was more significant at lower frequencies. [Pg.1648]

It is significant that the reinforcement degree corresponds to a class of polymer forming a nanocomposites matrix. The largest values of / are obtained for polymers whose chains are able to stretch on the silicate platelet surface (rigid-chain polyimide, crystallising polypropylene and thermotropic liquid crystalline polyester), intermediate values for polymers whose chains are able to stretch only partly (polycarbonate, poly (butylenes terephthalate) and amorphous polyamide-6) and the smallest values for nanocomposites on the basis of epoxy polymer, the capability of chains stretching of which decreases sharply because of the availability of transverse covalent bonds network [30].
